Recently, the National Institutes of Health (NIH) published this article regarding renal artery stenting, a common surgical procedure to treat patients with renal artery stenosis.  As noted in the article, renal artery stenosis occurs in 1 – 5 % of people who have hypertension, an extremely common disorder affecting approximately 78 million Americans.  For those with hypertension who exhibit signs of renal artery stenosis, many times the renal arteries are stented, to prevent further injury to the kidneys.  When untreated, renal artery stenosis can lead to chronic kidney disease, which comes with its own symptoms and comorbidities.
